SPECIFICATION forming part of Letters Patent No. 613,967, dated November 8, 189$.

Application filed October 2, 1897. Serial No. 653 ,894. (N model.)

To all whom it may concern: Like reference-numeralsindicate like parts Be it known that 1, JAMES E. CARTER, a in the different views. citizen of the United States, residing at g V The casing 1 is formed with an elongated Bridgeport, in the county of Mono and State slot2 in the front face thereof and has mount- 5 of California, have invented certain new and ed for rotation on the inside thereof the disuseful Improvements in Station-Indicators; pensing and storage rolls 3 and 4, respecand I do hereby declare the following to be a tively, the said rolls each being hollow and full, clear, and exact description of the inhaving coiled springs 5 located on the inside vention, such as will enable others skilled in thereof. The said springs are so connected 1c the art to which it appertains to make and to the rolls 3 and 4 and to the shafts upon use the same. which they turn that when one of the springs This invention relates to station-indicators is wound up the other will be unwound. Atof that'class in which are employed a casing, a tached at each end to the rolls 3 and 4 is a dispensing and a storage roll, a guide-roller, band or strip 6 of suitable fabric, the same 15 and a stripof suitable material having the having printed upon its outer surface the names of the different stations printed in mg names of the dilferent stations at regular inular order thereon, said strip passing over the tervals apart.

Located directly beneath the guide-roller 7 In the drawings forming part of this speciand extending transversely thereof is a roller fication, Figure 1 represents a perspective 10, provided with a spirally-arranged groove view of my device in operative position. Fig. 11, extending from one end thereof to the 5 2 is an elevation with the end of the casing other. The said roller 10 is mounted at each removed.

The uprights or stand- I00 50 mechanism for raising and lowering the ards 13 being slightly longer than the upclutch. rights 12, the chain 16 extends from the rollers 10 to 14 in an inclined direction. In the upper ends of each of the uprights 12 and 13 is formed an elongated slot or opening 17, in which is mounted a guide rod or bar 18, the same being normally urged downwardly by a spring 19, each end of the rod or bar 18 being formed with a shoulder 20 for a purpose which will presently appear. On the guide rod or bar 18 is mounted to slide aclutch2l, having two oppositely-disposed outwardlyspring-pressed engaging members 22 23, the same being provided with pointed ends and beveled sides. The clutch 21 being located between the two parts of the endless chain 16, the engaging portions 22 23 thereof are adapted to engage one or the other side of said chain according to the position of the guide rod or bar 13. The said clutch 21 is normally held downwardly or at a point adjacent to the roller 10 by means of a coiled spring 2+1, which surrounds the guide-rod l8 and engages a stop 25 at one end thereof. The rod or bar 18 is moved bodily to its upper or lower position by means of a shiftingbar 26, which is located just beneath the bar 18, fits within the slot or recess 17, and is provided with a knob or handle 27 upon one end, which projects out through the side of the casing 1. The said shifting-baris formed at points adjacent to each end thereof with lugs or projections 28, which have inclined side edges adapted to bear against the shoulder 20 on the rod 18, so that when the said shifting-bar is drawn outwardly the guide rod or bar 18 will be forced upwardly, bringing the engaging portion 22 of the clutch 21 into operative connection with the upper part of the chain 16. \Vhen the same is forced inwardly, the guide-rod 18 will be thrown downwardly by the spring 19, so that the engaging portion 23 of the clutch will be in operative connection with the lower portion of the chain 10.

By the construction just described it will be seen that upon the rearward movement of the clutch 21, through the actuation of the spring 24, the engaging member 22 or 23, as the case may be, will slide freely over the links of which the chain 16 is made up by reason of the fact that said engaging portions are formed with inclined or beveled side edges. Upon the opposite movement, however, of said clutch the engaging member 22 or 23 will contact with the adjacent link of the chain 16 and move said chain with it.

The mechanism by which the clutch 21 is moved upwardly or outwardly will now be described.

Pivoted at one end to the base of the upright 13 is a lever 29, which is connected at its free end to the clutch 21 through a wire, cord, or other analogous device 30. The said lever 29 also has connected to it an armature 31 of an electromagnet 32, which is located on the inside of the casing a short distance outside of the upright 13. The said electromagnet is energized by a suitable battery,

through the circuit-wires 33, from a suitable point adjacent to the conductor or other train oflicial whose duty it is to operate the indicating mechanism. It may also be energized automatically by locating loops of live wires 34. at each street-crossing,with which contact is made by circuit-wires 35 35, attached to the usual trolley-pole or other suitable support. It will be seen that when the magnet 32 is energized it will attract to it its armature 31, which, being connected to the lever 29, will draw outwardly the free upper end thereof. This action of the lever 29 will, through the cord or wire 30, draw the clutch 21 against the action of the spring 24 toward the roller 14, moving the chain 16 in one direction or the other, according to which one of the engaging portions 22 or 23 is in operative connection therewith. This will rotate the spirally-grooved roller 10 in a corresponding direction and will turn the guide-roller 7 so as to wind the strip 6 from the roll 4, or vice versa.

In connection with the foregoing parts I employ an alarm device which is actuated at each time the indicating mechanism is operated. This consists of an ordinary bell 36, having a trip-lever 37, carrying a hammer 38 upon one end thereof and normally lying within the path of movement of the clutch 21.

From the foregoing description it will be seen that I have devised an extremely simple and effective station-indicating device which may be operated from a distant point and in which the indicating-strip may be reversed according to the direction in which the train or car is moving by merely forcing inwardly or drawing outwardly a shifting-lover. Any number of indicating devices may be employed that may be desired. All may be connected to the same circuit, and all may be operated simultaneously by a single action upon the part of the proper officer.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a station-indicator, the combination of a guide-roller having a series of pins or projections thereon, a strip or band containing the names of the different stations passing over said guide-roller and provided with openings in which said pins or projections are adapted to fit, a spirally-grooved roller in the grooves of which said pins are adapted to fit, and means for rotating said spirally-grooved roller, as and for the purpose set forth.
